[FFmpeg-devel] [PATCH v2 0/2] lavf/isom: support for demuxing MPEG-H 3D Audio in MP4

[Yuki.Tsuchiya]

Hi,
                                                                                                                                                                                
Here is the sample content of the MPEG-H 3D Audio.

> If this patch allows remuxing with ffmpeg (I believe it does) but if the output file is not compatible with something that supports mpeg-h 3D audio, the patch has to be changed before it can be committed. 
I added some codes for copying mandatory boxes. I confirmed with following command that the remuxed.mp4 is compatible with MPEG-H 3D Audio standard.
                                                                                                                                                                                
  ffmpeg -i mpegh_3d_audio_mhm1_sample.mp4 -codec:a copy remuxed.mp4
